DAFWA researcher Ravjit Khangura standing in a field of canola... Dr Khangura said the main control tactic was to reduce the frequency of host species, such as canola and lupins, and it was recommended growers avoid planting canola on paddocks with high sclerotinia levels during the past three years... "Previous research in WA's northern cropping region has shown that applying a single fungicide spray is often effective in reducing canola yield losses from sclerotinia when the crop is at the 15 to 30 per cent flowering stage (coinciding with the onset of spore release) and conditions are conducive to disease," she said...

Western Australia's coming cropping season is expected to be a high risk year for blackleg disease in canola but growers can take steps to minimise the damage... Department of Agriculture and Food (DAFWA) plant pathologist Ravjit Khangura said growers should select resistant varieties, not seed into or close to last year's canola stubble and, if warranted, use a fungicide seed dressing or fungicide-amended fertiliser... The National Brassica Pathology Working Group, of which she is a member, is concerned that growers will face the risk of crop failure due to blackleg if attempting to grow canola on canola...
